I designed a couple of knit beanies (known as toques in Canada) using Printful. I got them shipped to my house and I think they look great! Here is my review of these beanies/toques and a quick walkthrough on how I created them in Printful.
Using Printful, you can create and sell custom products online. Printful interfaces with online platforms like Etsy, Shopify, Wix, ebay and tons more. They have some really high-end apparel and you can create sample orders that come right to your house.
